M. and Konstantinov, D.}, issue = {2}, journal = {JETP Letters}, month = {Sep}, note = {The experimental detection of the Bose-Einstein condensate of magnons in coupled nuclear-electron spin precession in antiferromagnets brings the prospect of its use for magnonics and computer calculations. In particular, an attractive feature of such systems is a relatively large spin coherence time compared to traditional iron yttrium garnet samples. However, the observed Bose-Einstein condensation of magnons contradicts the Suhl-Nakamura model and the Bloch equations, which are usually used for these systems. The results of a direct experiment in antiferromagnetic MnCO3 performed in this work indicate that the Suhl-Nakamura model and the Bloch equations cannot adequately describe the coupled nuclear-electron spin motion at large levels of magnon excitation.}, pages = {95--100}, title = {Features of the Coupled Nuclear–Electron Spin Precession in the Bose–Einstein Condensate of Magnons}, volume = {112}, year = {2020} }
